They are indeed called wind flowers but they prefer dappled shade and some shelter I think. However, they are adaptable plants
Obelixx, I grow the white variety Honorine Jobert. It's a lovely flower but I think it's the most imvasive variety. Mine is in a dry spot but sheltered and where it can't invade.. More moisture and it would be better but I won't let it anywhere near my precious borders.
I suppose an area dedicated to jap anemones....providing good fertile soil, dappled shade and moisture...would look fantastic. If I did that I would fill it with bulbs...spring and summer....to create a long period of colour. Would ensure though that the anemones could not escape
